The objective was to determine the 10-year oncological safety of nipple-sparing mastectomy (NSM) in patients diagnosed with ductal carcinoma in situ (DCIS). The use of NSM preserves the nipple-areola complex (NAC). As residual fibroglandular breast tissue can remain behind the spared NAC, its use for patient with breast cancer is controversial. The oncologic outcomes and complication rates after performing NSM compared to other techniques are still under debate and a concern when treating patients with breast cancer...

Patients who undergo breast reconstruction experience higher complication rates if they have had a history of radiotherapy. However, implant-based reconstruction confers significantly higher complication and reconstruction failure rates compared with autologous reconstruction. This article analyses the factors that contribute to the complications of the different breast reconstruction modalities and the strategies described to mitigate these problems.

Permanent seed implantation (PSI) brachytherapy is a highly conformal form of radiation therapy but is challenged with dose inhomogeneity due to its utilization of low energy radiation sources. Gold nanoparticles (AuNP) conjugated with electron emitting radionuclides have recently been developed as a novel form of brachytherapy and can aid in homogenizing dose through physical distribution of radiolabeled AuNP when injected intratumorally (IT) in suspension. However, the distribution is unpredictable and precise placement of many injections would be difficult...

BACKGROUND: Implant-based breast reconstruction is the most common type of reconstruction after postmastectomy radiation therapy (PMRT). The impact of the timing of PMRT to a tissue expander or permanent implant is not well understood. The purpose of this systematic review was to evaluate outcomes in implant-based reconstruction and the timing of PMRT. METHODS: A review of the English literature in the PubMed/MEDLINE database (2000-2016) was performed to identify all articles on implant-based breast reconstruction and PMRT...

BACKGROUND: Capsular contracture is a devastating complication of postmastectomy implant-based breast reconstruction. Unfortunately, capsular contracture rates are drastically increased by targeted radiotherapy, a standard postmastectomy treatment. Thy1 (also called CD90) is important in myofibroblast differentiation and scar tissue formation. However, the impact of radiotherapy on Thy1 expression and the role of Thy1 in capsular contracture are unknown. METHODS: The authors analyzed Thy1 expression in primary human capsular tissue and primary fibroblast explants by real-time quantitative polymerase chain reaction, Western blotting, and immunohistochemistry...

PURPOSE: Differentiating tumor from its surrounding soft tissues is challenging for x-ray computed tomography (CT). Fluorescence molecular tomography (FMT) can directly localize the internal tumors targeted with specific fluorescent probes. A FMT system was developed and integrated onto a CT-guided irradiator to improve tumor localization for image-guided radiation. METHODS: The FMT system was aligned orthogonal to the cone-beam CT onboard our previously developed image-guided small animal arc radiation treatment system (iSMAART)...

Breast cancer is the most common malignancy diagnosed among women and represents a heterogeneous group of subtypes. Radiation therapy is a critical component of treatment for breast cancer patients. However, little is known about radiation response among these intrinsic subtypes. In previous studies, we identified a significant induction of FAS after irradiation in biologically favorable breast cancer patients and breast cancer cell lines. Here, we expanded our study and investigated radiation response in a mouse model of breast cancer...

Radiation therapy is a critical component of breast cancer management following breast-conserving surgery. Post-radiation sequelae are greater in women with larger breasts, given the need for higher doses and dosing heterogeneity. The goal of breast reconstruction post-mastectomy is to improve the quality of life and add no more health risk. The optimal reconstruction should make the patient feel as natural as possible. Reconstruction of a large-sized breast with aesthetically satisfactory outcome poses a challenge to the breast surgeon...

INTRODUCTION: The reconstruction of the Nipple-Areola Complex (NAC) is the last step and a key part in breast reconstruction. The technique to be used should be chosen as to avoid any complications on previous reconstruction steps. The use of local flaps for NAC reconstruction could be associated with implant exposure especially in the presence of a history of radiation therapy. The pure dermal flap could be indicated for the nipple reconstruction after breast reconstruction by implant after radiotherapy...

BACKGROUND: In the debate on reconstruction of the irradiated breast, there is little information on associated health care resource use. Nationwide data were used to examine health care resource use associated with implant and autologous reconstruction. It was hypothesized that failure rates would contribute the most to higher average cumulative cost with either reconstruction method. METHODS: From the 2009 to 2013 MarketScan Commercial Claims and Encounters database, irradiated breast cancer patients who underwent implant or autologous reconstruction were selected...
